Brie's Bling Rings: 10 Megawatt Rings for Brie Larson\nBrie Larson has already won an Oscar this year for her starring role in Room. As if her year could get any better, the actress has just confirmed her engagement to her musician boyfriend Alex Greenwald. (The two have actually been engaged since March when they were in Tokyo, but it was only made public after her recent Saturday Night Live performance over the weekend.) She’s been known to turn heads with her stunning red carpet choices, like the gold Calvin Klein dress she rocked at the Golden Globes this past year and that light blue Versace gown at the SAG Awards; now, she needs a glamorous ring to match. Here, 10 megawatt options for the Hollywood It girl.\nAlex Greenwald and Brie Larson in Gucci.
